To all whom it may concern:

Be itknovvn that I, WALTER J. ST. Ouen, a-citizen of the United States, residing at Elyria, in the' county of Lorain and State 'of Ohio, have invented certain new and useful Improvements in Warning-Signal Devices; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

`Myinvention',relates to av unitary structure, consisting of-va lampand Warningpsig nal device adapted to be employed one ve hicle, such as an automobile, motor boat: vor

the like, one of the objects of my inyention being the production of a compact l. structure of this kind'whch serves for both lighting and signaling purposes. The lamp either-With or Without a vspecial refiector, may b'e" mounted inside the resonator or bell `owthe horn, thus producing a' unitary .structure and vreducing the ,number of :time` tures attached to the vehicle, the number ot parts to be 'kept clean andfurnishing a better protection 4for the lamp. These advantageswill be better appreciated When it is considered how many xtures are secured to .the sides of an automobile, when the fixtures i areindiyidual units.

' Other ob'eets of my invention and the invention itself will be best understood by reference to the following descriptionwhen taken in connection with the accompanying illustrations showingr specific embodiments of my invention, while the scope will be particularly pointed out in the appended claims. y i

mrn which is adapted to `be used.'upon=eaii automobile or other vehicle to which sucli devices aresuited. This horn, in the form of my invention shown, consists of a frame plate 2, upon which magnets 3 are mounted A diaphragm 4 is Vfastened to the' frame vby suitable fastening means, such asr screwsri At 6 is shown an armature Whichisrcone trolled by tthe magnets and which is adapted to transmit blows to the diaphragm, prei erably vthrough an anvil 7.; While I have 'shown this form offwarning signal device, d5

any suitable` form" may lbe usedrWAjresona 'tor'` Siis mounted on the front'of the vhorn and is preferably parabolic inf shape. =A parabolic reflector S'is mounted Within the resonator 8,' being spaced' therefrom, leaving anfopening between the resonator and the 'edge Aof' the reiector `to permit'the'passage of 'sound 'waves outward. In the form Shown in Rigs. 1 and 5 spacing membersll are 'employed for this purpose. These mein- T725 bers'are'fastened at'olie end to the'reson tor 8 by screws or other suitable fasteni D. means l2 and at the other end to the refi'eci tor 9 by suitable fastening'means.I3;v A lamp 141.` is mounted in the reflectorv Qgpr'ef- 8b erably in the vfocal point of said reflector. This point may also be the foc'alpoint of the resonator. A glass 15 is mounted in the opening end of the reflector 9, being clamped thereto by a member 16. The sound Waves 85 which are causedv bythe vibratile member 4, either'pass directly through the opening' ll or else strike lthe back ofthe' refiector 9. Thev back of this reflector is preferably polished so las tov maire the rear surfacelikeivise 9` a good reflector. Sound waves striking this surface, will be either reflected to the inner surface of the resonator or directly out through the opening 1 1. When striking the bev reflected until they pass outward through the-opening 1l. It will thus be seen that the character of the signal will not be materially altered or the signaling: interfered with by the presence of the reiiector and lamp inside of the resonator.

In the forni` shown in Fig. 3, the rays of light emanating :trom the iamp 14 are re- 'lected by the resonator S', ne special reiec tor being provided for the iainp, 2.95 resonator 8' serving both reactions. ne

lamp is here supported bybraekets 20, each Connecting the lamp socket 21 to the rear of the resonator or the front of the frame 2. lVhile I have shown only a portion of the resonator as parabolic, it will be apparent that the entire resonator may be so made if desired, but it is desirable that the. part which reflects the lightl waves. should be so made, the lamp being prc'erably mounted in the focal Vpoint of the parabolic part of the resonato as in the form shown.

In Fig. 4, the mounting of the lamp is similar to that shown in the `form shown in Fig. 3, a lamp 14 being mounted in a socket `21 connected by brackets .20 to the frame piece "2 or the rear of the resonator S". The lamp is provided ,with a special reflector 9". This reflector is, however. small in coniparison with the resonator. so that some of the rays of light from the lamp are not reflected thereby. A portion of the resonator shown at Q5 is made parabolic so as to reflect the rays of light which pass through the front of the reflector and impinge thereon. The lamp is placed in the focus of the portion of the resonator which is madeV parabolic, for the reason that when a source of light is placed in the focus of a parabolic reflector, tbe rays incident thereon are reflected exactly parallel to the axis. lf it is desired. the entire resonator may be made parabolic., though it will be apparent that for the design shown in F ig. 4, the annular portion alone. is suflicient.

The lamp and the signaling device.. if an electrical signaling device is employed, may

Abe connected up with the same circuit connections as shown in Fig. where a common battery B is. employed. 'lhis battery is con nected b v conductors 50, 51 `and 52 with both the lamps and the signaling devices. the circuit of the signaling devices being controlled by a switch S and that of the lamps by a second switch S'.

It will be apparent that any form of warning signal device, that any form of lamp or that any form of' reflector may be cinployed in connection with my invention and that numerous and extensive departures from the forms and details of' the apparatus here shown may be made witb'out departing from the spirit. oll this invention. the same being herein shown solely for the purpose of clearly illustrating specific embodiments thereof.

Having thus described specific embodiments of my invention, what I desire te claim is:

1. In combination, a warniligfsignal de- ,viee. a resonator therefor, a lamp reflector, a lamp in said reflector and means to mount said lamp and reflector within the resonator, the walls of the resonator extending beyond the walls of the reflector when the reflector is mounted in the resonator, the light rays from the lamp in the reflector impinging upon such extended portion of the reflector and being reflected thereby. said extended portions having a focal point and said lamp being mounted at the focal point thereof.

ln combination. a warning signal de vice. a resonator therefor, the edge of said resonator being flared outward to reflect light rays, a light reflector mounted in said resonator. and a lamp in said reflector, said flared part reflecting the rays of light from said lamp. e

3. In combination, a warning signal device. a lamp reflector. means to mount said lamp reflector in front of said warning signal device. a lamp in said reflector, a resonator for said warning signal device mounted in front thereof and extending beyond the reflector, said extending part reflecting light l'rcm said lamp, a part. of the extended portion of the resonator having tbe same focal point and a curvature of the same nature as the reflector.

In combination, a warning signal device. a lamp reflector of parabolic curvature mounted in front thereof. a lamp in said reflector at the focal point thereof, a resonator in front of said warning signal device and extending beyond the reflector. said extending part reflecting light fronrsaid lamp, a part of the extended portion of the resonator being of parabolic curvature on its interior surface and having the same foral point as the reflector.
